Leap Of Faith

This English phrase may sound rather daring and it likely should. It is usually used to refer to an act of bravery on some level. The act of bravery being spoken about may be relatively small. If so, then the phrase is used somewhat humorously.

For Example:

“He took a leap of faith when he gave up watching television and started jogging instead.” “She took a leap of faith when she tried a new flavor of ice cream.”
